Balun nRF52

[vidal]

Hello,

Can you share with us the balun of the nRF52 chipset or at least the ZLoad equivalent, that is R + jX value.

The Balun if the nRF52 is a 6-Element Balun or 4-Element Balun?.

Thanks in advance.

Jose.

There is no balun required for nRF52 SoC's. All the antenna connections are single ended.

Only nRF 51 chipsets have balanced antenna connections and require a balun.

I want to know the Zin because your reference design is not good at all. You can see this post:

Please can you contact with Nordic in order to get the internal balun.
